WebThe null hypothesis is that there is no association and the $\chi^2$ test examines this hypothesis. There are rules to follow when using a $\chi^2$ test, listed below. No category has a mean of less than $5$. The categories should be as natural as possible. Keep to the raw data. Avoid categories that vastly exceed others. Goodness-of-fit Tests ... WebDec 24, 2024 · That said, there are a few counts in bins very far away from the mean. That means when computing the χ 2 statistic using very small bins, I have a few terms like: ( O b s e r v e d − E x p e c t e d) 2 E x p e c t e d = ( 1 − 0.05) 2 0.05 = 18.05. This leads to a high χ 2 statistic, and thus a low p-value. As expected, the problem goes ...
